Campbell) A. Honma White Paper R&D project

8. Engineering R&D (discussion forum in 2008, all LHC experiments + DT participating, moderated by L.Linssen) We expressed interest to participate in a couple of common engineering R&D activities, e.g.  Detector cooling o CMX/DT/TE-CRG team has started to study suitability of CO 2 cooling for larges scale detectors. Pilot case: CMS pixel det. upgrade; (≠ CO2 cooling plant development). Timescale 18 months. o is now part of WP11 / DCP.  Reverse engineering = 3D models for high accuracy reconstruction of built structures. DT/BE- ABP. 1 shared fellow. Has started. Applied to ATLAS Inner Tracker services.  Material for future detectors (structural, thermal, radiation hard, pipework and joining techniques). Not yet really started. Overlaps a bit with WP7.

9. 9 General approach for new projects Avoid fragmentation into too many mini projects (~1-2 FTE) Collaborate with experiment’s CERN group Try to apply available expertise and infrastructure (DSF, bond lab, thin film lab, irradiation facilities, mechanical workshops, gluing lab...) Find interesting projects to keep phys/eng/tech up to date in new technologies  Aim for ~2-3 main projects with major hardware deliverable + a couple of smaller projects. + engineering/integration/installation support Current involvement + vague options in LHC upgrade projects … (<2 FTE) ATLAS upgrade: participation to PO / engineering + … CMS upgrade: engineering, cooling study for upgraded pixel, pixel luminosity telescope, humidity measurement LHCb upgrade: VELO upgrade (40 MHz), RICH ALICE upgrade: VHMPID, pixel (cooling) TOTEM upgrade: Large GEM (T1), part of WP5 … we would like to start soon! … has already started

10. 10 Detector cooling Autumn 08, DT proposal: Launch a common detector cooling activity in PH-DT (in analogy to our gas systems activity), preferably merged with EN/CV-DC section. Many discussions took place, on various levels. In the end, the merger was refused by EN management. A CERN wide Detector Cooling Project (~Working Group) was recently created, chaired by M. Battistin. DT is represented by P. Petagna. Current DT situation – not 100% clear -We contribute (modestly) to consolidation of CMS C 6 F 14 system (leak testing, rack assembly) -We are involved in a CO 2 cooling feasibility study for a future CMS pixel det. How to continue ? -We still think that detector cooling is of highest importance for upgrade -We still want to contribute to detector cooling: on-detector thermal aspects, piping, joining techniques; to a lesser extent but not excluded: cooling plant design/construction -We still see synergies with our gas systems and magnet controls activities

11. 11 Detector cooling Near future plans -PhD project: Dynamic performance and process modeling for the future cooling systems (A. Moraux) -Recruitment of 2 engineers, directly related to detector cooling (incl. consolidation, operation of existing systems). -Look for projects and opportunities to gain expertise and apply our resources
